Copper. Nickel. The removal of some heavy metals such as Mn (II), Co (II), Ni (II), and Cu (II) from aqueous solution is studied using a raw kaolinite. The sorption of these metals on kaolinite conformed to linear form of Langmuir adsorption equation. Langmuir C (m) constants for each metal were found as 0.446 mg/g (Mn).

Copper (I) chemistry is limited by a reaction which occurs involving simple copper (I) ions in solution. This is a good example of disproportionation-a reaction in which something oxidises and reduces itself. Copper (I) ions in solution disproportionate to give copper (II) ions and a precipitate of copper. The reaction is:
